User should not provide bridge address at first place, I guess this is a
protection in case user provides bridge address by mistake.
In that case no device will be probed and user won't have any idea why.
I think a log in dmesg saying bridge device is provided may help to the user.

I'll add a dev_warn as we actually encounter this issue on old silicon 
revisions due to bridge address equaling a PF.
It's not a user error in such case and just needs to be ignored.  So 
adding this generic check allows such to occur.
For other use cases like you mentioned it would be a user mistake.

This is same as armv8a machine type, is it required to add new "stingray"

Can you please update driver documentation (doc/guides/nics/bnxt.rst) with new
device information.

Also it can be good to update release notes to announce new device support.

How to use this variable, I tried following but kernel modules are still in same
place:

- make RTE_KERNELDIR_OUT=/tmp/kmod O=ferruh DESTDIR=/tmp/ferruh
- make RTE_KERNELDIR_OUT=/tmp/kmod O=ferruh DESTDIR=/tmp/ferruh install
- make RTE_KERNELDIR_OUT=/tmp/kmod O=ferruh DESTDIR=/tmp/ferruh modules_install

/tmp/kmod not created.

And what we are fixing here, what was wrong with old code?

> source directory RTE_KERNEL is used.

${RTE_KERNELDIR} is used as external Linux kernel source folder, why we are want
to put artifacts into kernel source?

RTE_KERNELDIR already exists in Makefile.  Are you able to override it?

Old code puts the intermediate object files in the kernel source 
directory.  This doesn't work when building an external module in 
openembedded recipes.  We need the Makefile change to be able to able to 
specify the kernel and output directories separately.

I just kept the default behaviour the same as what it does today.

Good question.  We could have tuning or other differences in the future 
but it looks like we can use the armv8a machine.
I think we can get rid of rte.vars.mk for now.

Please help me a little more, can you please list your commands?

Before your patch, what I do:

export RTE_KERNELDIR=~/development/linux/linux
make defconfig
make    <--- After this kernel modules in ./build/kmod/*.ko
make DESTDIR=/tmp/for-scott install

kernel modules are installed into /tmp/for-scott/lib/modules/`uname
-r`/extra/dpdk/*.ko

Here `uname -r` is wrong but your patch is not related this.

I am using RTE_KERNELDIR a lot since I am compiling with various kernel
versions, not seen .ko files goes into source folder, what is your command line?



Or _after_ your patch:
export RTE_KERNELDIR=~/development/linux/linux
export RTE_KERNELDIR_OUT=/tmp/kmod
make defconfig
make    <--- After this kernel modules in ./build/kmod/*.ko

Getting following build error:
/bin/sh: scripts/mod/modpost: No such file or directory
make[7]: *** [.../development/linux/linux/scripts/Makefile.modpost:92:
__modpost] Error 127
make[6]: *** [.../development/linux/linux/Makefile:1558: modules] Error 2
make[5]: *** [Makefile:146: sub-make] Error 2
make[4]: *** [../mk/rte.module.mk:54: igb_uio.ko] Error 2

Can you please describe how this variable intended to be used?

Re: [dpdk-dev] [PATCH 3/4] mk: allow kernel artifacts to be located in output directory

[Scott Branden]

Hi Ferruh,

Somehow I did not receive your other email so Ajit fowarded it to me.  
So I am responding to it here.

Sorry for the previous confusion:  RTE_KERNELDIR_OUT specifies the 
location of the output of the kernel artifacts, not the output of the 
DPDK build artifacts.

Here is an example to use RTE_KERNELDIR_OUT:

export ARCH=arm64
export CROSS_COMPILE=~/gcc-linaro-aarch64-linux-gnu/bin/aarch64-linux-gnu-
export CROSS=aarch64-linux-gnu-

export RTE_KERNELDIR_OUT=~/test/linux-out
export RTE_KERNELDIR=~/test/linux
cd $RTE_KERNELDIR
make defconfig O=$RTE_KERNELDIR_OUT
make -j 8 O=$RTE_KERNELDIR_OUT

cd ~/test/dpdk
make config T=arm64-stingray-linuxapp-gcc
make

Note:

With this example you will likely hit a few compile errors as latest 
dpdk has compile bugs with unused variables/type mismatches in the code.

Regards,

  Scott

I guess using "~/test/linux-out" as RTE_KERNELDIR also works (because of
"source" link), but your patch looks more proper way.

There are a few documents for build parameters, can you please update them too:
doc/guides/prog_guide/dev_kit_build_system.rst
doc/guides/linux_gsg/build_dpdk.rst <-- not sure about this one, please check
doc/build-sdk-quick.txt  <-- this is "make help" output

I didn't get the error, if you observe build error please report or better a
patch to fix is always welcome :)

Actually, you may be correct.
Perhaps all this requires is a documentation change.
Does any of DPDK build system actually require to know where the kernel 
source directory is?
Or, does DPDK only require to know where the kernel artifacts exist (ie. 
generated headers)

Looking at the documentation it is a little confusing.  Each one 
describes something different.
guides/linux_gsg/build_dpdk.rst
99:    the ``RTE_KERNELDIR`` environment variable should be used to 
point the compilation at a copy of the kernel version to be used on the 
target machine.

guides/prog_guide/dev_kit_build_system.rst
297:*   RTE_KERNELDIR: This variable contains the absolute path to the 
kernel sources that will be used to compile the kernel modules.

build-sdk-quick.txt
24:    RTE_KERNELDIR    linux headers path

In guides/prog_guide/dev_kit_build_system.rst.  If "kernel sources" was 
changed to "linux headers" my change may not be needed.  I'm doing some 
more testing now with RTE_KERNELDIR set to linux-out in other DPDK builds.

Yes - we have patches being created for 64-bit build warnings/errors

Both are required, kernel source is required because of some headers, there are
multiple components depends on kernel headers, also kernel artifacts are
required like kernel config mainly for building kernel modules.

I believe it is not just "linux headers", it is more like "compiled kernel source"

Hi Ferruh,

We dropped this patch from the series - comment inline.

Yes - everything is provided in the linux-out directory.
I have no need for this patch and we have dropped it from the patch series.
Setting RTE_KERNELDIR to the linux-out directory allows DPDK to build.
